bah...I think its fine and you are doing well. There are always improvements you can make mate...dave is but another pair of eyes and that is a good thing mate. Better to have comment than none at all I say....I think he is also making light of the model LOL (depends on how many beers he has had).

I think now the red light has to go...it is taking away the green hue mate..which I might add has given the image that old B&W TV about to die feel..if you know what I mean.

Keep going man.....I like it...make a good tattoo actually....if you finish it well I might even consider asking your permission to get it in ink on my arm.

cheers bullet

edit: I still think the main character should be B&W with the green fog/hue JUST visible in colour...it gives it more menacing a feel IMO.
